Brief Summary:

This is a multicenter, single-arm phase I clinical trial.The study process was divided into: screening period, sampling and production period, clear lung pretreatment period, treatment and observation period, and follow-up period.

The study is designed to enroll 20-31 subjects, with 14-20 subjects expected to be evaluable, in an "autologous tumor-infiltrating lymphocyte therapy" regimen that includes:

  1. Clear lymphatic pretreatment (FC regimen: cyclophosphamide + fludarabine).
  2. GT101 infusion.
  3. post-infusion treatment (interleukin-2 intravenous push).

Primary Outcome Measures :
  1. Safety Profile Measured by Grade ≥3 TEAEs [ Time Frame: 3 years ]
    To characterize the safety profile of autologous TIL injection(GT101) in patients with relapsed/metastatic advanced solid tumor as measured by the incidence of Grade ≥ 3 treatment-emergent adverse events (TEAEs)

  2. Objective response rate [ Time Frame: 3 years ]
    To evaluate efficacy parameters such Objective Response Rate (ORR) per RECIST 1.1, as assessed by the Investigator

  3. Progression-free survival [ Time Frame: 3 years ]
    To evaluate efficacy parameters such Progression-Free Survival (PFS) per RECIST 1.1, as assessed by the Investigator

  4. Overall survival [ Time Frame: 3 years ]
    To evaluate efficacy parameters such Overall Survival (OS)
